Notice: the actual input pressure (P input) + the pressure at zero delivery
rate (P zero delivery rate) must always be lower than the maximum
authorised operating pressure (Pmax). If the maximum authorised
operating pressure is exceeded, the mechanical seal and the roller
bearing can be damaged or their life span reduced.
P input + P zero delivery rate ≤ Pmax
Refer to the pump plate for the maximum operating pressure: Pmax
